What does that bike weigh?

about a pound

I think it's just south of 50 pounds

@Laughing Grass is correct, 47lbs as it sits, but I’m thinking of getting rid of the kickstand, and seeing if I have some carbon fiber handlebars lying around.
The blue paint totally has metal flake in it too, the paint job is surprisingly good

Steel frame. I’m not a small guy, and when I put a 1000 watt motor on it, it may put a little more than “factory recommended” stress on it...haha
If something goes wrong, I need something that will bend at 35 miles an hour, not catastrophically fail. I felt like a steel frame was the way to go as far as safety is concerned. I probably wouldn’t notice a fine crack in an aluminum frame, and if that thing fell apart at speed I would be in a world of hurt

Well done! No skips or delayed shifting.
It looks great all around! I honestly expected it to look crappy. I’d ride it!
47 lbs isn't really that bad. Most full suspension mountain bikes in the $2,000 range are pushing 35 lbs. Almost everything on my bike is carbon including the rims and all the metal parts are titanium except the rotors, spokes and cables and it still weighs in a 27 lbs for a small.

Eh what? A fine crack is a fine crack.....shit's gonna hit the fan no matter what material is breaking.

Steel is way less likely to crack. More likely to bend. Way more forgiving...
normally I wouldn’t care, but since I had a kid a couple years ago, I have a newly vested interest in staying alive for the foreseeable future...lol

Thanks! Yeah once I mess with the limiting screws and bend it another millimeter or two, it should shift like clockwork.
I even have a rapid fire trigger shifter on the way to replace the godawful twist shifter...lol
You DO have quite a sexy rig

I bet you say that to all the girls
Full disclosure I didn’t pay for that bike, it was so far outside my budget. I had my heart set on a orange specialized stumpjumper when this opportunity came along. I do wish the Kona was orange.
I wasn’t going to say anything, but those non-indexed grip shifters are pure trash! Constant ghost shifting while you’re riding... probably the best upgrade you could have made. That and ditching the kickstand

Mild steel has a peculiarly high “ work of fracture”, the energy needed to break it in two. Aluminum tears more easily for a given strength. Carbon has a very high modulus, so is strong for its weight, but its work of fracture is low. It snaps.
So when steel is taken past the elastic limit, it absorbs a lot of energy in bending and then more in tearing, reluctantly and with much complaint. Meta called it.

Don’t forget @DarkWeb complimenting your fine ... oh look! Gravel!!I bet you say that to all the girls

This all depends on the alloys used and if heat treating is also used......let's not forget geomotry.....steel is also not usually hydroformed for bike fabrication. Both my red and black bikes where hand built in alu.

Most aluminum bikes aren’t rated for a rider over 250 lbs, which unfortunately at the moment, I fall into that category. Part of the reason I started this whole project was to get me out there and more active, hopefully get back to a reasonable weight for a 6’0” male
